Mamdani celebrates victory in 'reborn' New York City

During her victory speech in the Virginia governor's race, Abigail Spanberger told the cheering crowd, "Tonight we sent a message."

The message to Virginia, the country and the world, she said, is that Virginia "chose pragmatism over partisanship."

"We chose our commonwealth over chaos," she said. "You all chose leadership that will focus relentlessly on what matters most -- lowering costs, keeping our communities safe and strengthening our economy for every Virginian."

She said she intends to serve all Virginians.

"I have worked with anyone and everyone, regardless of political party, to deliver results for the people that I serve, and that's because I believe in this idea that there is so much more that unites us as Virginians and as Americans than divides us," she said.

Polls will remain open in parts of Passaic County, New Jersey, after unfounded bomb threats earlier in the day halted voting at locations across the northern part of the state, a judge ruled late Tuesday.

Voters will be allowed to cast their ballots until 9 p.m. ET at three schools in the Paterson area of Passaic County, which has been a swing county in recent cycles.
